specifically, fm3 constructed nine drones, varying from two seconds to 42 seconds, which repeat endlessly in the listener's ear until the "track" is switched to the next drone (or the two aa batteries run
out).

the machine has its own built-in speaker, in case one would like to fill a room with the drones, but there is also a headphone jack for more personal meditative experiences. there's a switch on the side that
allows for traversal of the tracks, and a dc jack (though an adapter is not included) for those who would like the buddha machine experience be truly endless.

in a way, it's like the cheapest pre-loaded ipod you'll ever be able to buy.
